Polyelectrolyte hydrogels perform interesting physical and chemical changes, such as motility and bend in the presence of electric fields and interaction with ionic surfactants. We think that ionizable groups of polyelectrolyte hydrogels play a vital role in these environments. In this work, we prepared three anionic polyelectrolyte hydrogels by two different routes, and micropipetts electrode was employed to determined negative potential in the gels.Our work showed that the gels reported herein all display a high degree of swelling with hydration and have a substantial negative potential in KCl solution and a simple mechanism was also described.

Modeling multiphase equilibria of mixtures comprising carbon dioxide (CO2) and organic compounds is a challenge for any equation of state. CO2 shows a highly nonideal phase behavior with most organic compounds, which is even more pronounced with hydrogen-bonding compounds. In this work, we have extended the Group-Contribution with Association equation of state (GCA–EOS) to represent vapor–liquid, liquid–liquid, and vapor–liquid–liquid equilibria of CO2 mixtures with primary alcohols. The final set of parameters has been challenged against an experimental database covering C1–C16 primary alcohols, temperatures from 230 to 573 K, and pressures up to 400 bar. Particular attention has been given to describe the critical curves for each binary system correctly, which means attaining the phase equilibria transformation of the CO2 + 1-alcohol homologous series as the alcohol alkyl chain length increases. This parametrization strategy allows reducing the risk of incorrect liquid–liquid split predictions. In addition, using a single set of parameters, fitted to binary data of CO2 with normal alcohols, the model is able to predict the phase behavior of binary mixtures not included in the parametrization procedure, comprising normal and branched alcohols. The GCA-EOS predicts properly the overall phase behavior, that is, the binary critical curves, without losing accuracy in the prediction of saturation points.

The phase behavior of the supercritical CO 2 + 1-alcohol homologous series for 1-octanol and higher alcohols is investigated. A literature survey revealed that sufficient data are available lower alcohols (1-decanol and lower) but data are limited for higher 1-alcohols. Data for CO 2 + 1-dodecanol, CO 2 + 1-tetradecanol, and CO 2 +1-hexadecanol were thus measured using a visual static synthetic method for T = 313− 353 K. Measured and literature data indicated that the phase transition pressures are very high (>28 MPa) for CO 2 + 1decanol and higher alcohols in the mixture critical region. Additionally, a temperature inversion (increasing temperature leading to decreasing phase transition pressure) is present in the mixture critical region and is more pronounced in systems containing higher 1-alcohols. The temperature inversion is postulated to result from the formation of alcohol multimers due to hydrogen bonding between alcohol molecules. From the phase behavior data as well as published upper critical end point and solid−liquid−liquid−vapor equilibria data, Type III phase behavior according to the classification of Scott and van Konynenburg is assigned to the systems CO 2 + 1-octanol to CO 2 + 1tetradecanol. However, for higher alcohols additional investigations are required to assign a phase behavior type. This systematic study hopes to aid future thermodynamic modeling attempts to describe the complex phase behavior of CO 2 + 1-alcohol systems.
